Specification of Letters Patent.

Patented June 10, 1919.

Application filed September 7, 1915. Serial No. 49,406.

To all whom it may concern:

Flame- Spreaders and Wick-Stops,of which the following is'a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates generally to oil or vapor burners and more particularly to a novel construction of wick stop together with means for-lifting the flame spreader.

One object of the invention is to provide a wick stop in connectionwith the wick raising spindle whereby the raising of the wick will be automatically stopped when the spindle reaches a definite position,

Another object of the invention is to provide a wick stop ofthis nature which can be and easily adjusted so as to comfor the consumption of the wick. Another object of the invention is to provide for the quick and easy elevation of the flame spreader so that the wick which has previously been raised to the proper position can be quickly and easily lighted before the same has reached its final orstopped position. V With these and certain other objects in view the invention consists in the novel features of construction and combination herelnafter' described and pointed out in the claims.

In the draWingsfOrming a part of this specification Figure 1 is a sectional view of an oil burner constructed in accordance with my invention, the elevated position of the flame spreader being indicated in dotted lines ,Fig. 2 is a detail sectional view on the line 22 of Fig. 1; and Fig. 3 is a detailed perspective view showing the lower end of the lifting rod and guide for the same.

In carrying my invention into efiect I employ a wickholder comprising the inner wick tube 10 and the outer wick tube 11 which are united as usual at their lower ends and receive therebetween the wick 12 which is incased in the perforated metal case 13 which is engaged by the wick raising wheel 141 carried upon the end of the spindle 15 which works through the tube 16 attached to h the projecting 'ing portion of the sleeve,

shaped stop member 23 is released portion of the the outer wick tube in the usual manner. Near the outer end of this. tube 16 is a sheet metald1sk'1'7. This disk has a depressed central portion 18, raised annular'shoulder' 19, an outwardly extending flange 20, and ats one po nt an oblique stop shoulder 21 unites the shoulder 19 and flange 20 serving to'limit the rotary movement of the wick raising spindle as hereinafter explained.

The spindle 15 passes upwardly through portion of the sleeve 16 and upon its outer end is provided with an operating wheel 22 by'means of which the wick raising spindle is operated. Upon the projecting portion of the sleeve 16 *between the disk 17 and hand wheel 22 I arrange a wick stop 23' consisting of a strip of metal bent essentially Uv shape, the parallel members 2 1 being positioned upon the projectthe upperend 25 bein serrated to engage the serratededge 26 of the wheel 22, and the lower end of this U shaped member is bent over the shoulder 19 and then providediwith an angled foot 27 which is adapted to be projected through a similarly shaped opening 28 punched in the flange 20 adjacent to the stop shoulder 21, and when this foot piece 27 is pushed down into'the opening disengaged from the serrated flange 26 of the hand wheel 22 and the wick can then be raised as desired. After the Wick has once been raised to the proper position the U and the spring 29 surrounding the. sleeve in the dished disk will serve to project the said U shaped stop device out into engagement with the wheel 22. This brings the wick raising spindleand wick stopping device into locked engagement and the wick can be turned down for the purpose of extinguishing the same but when moved up it will be impossible to move the wick higher than the proper position inasmuch as the stopv device in looked relation with the actuating wheelwill engage the stop shoulder 21 upon the "fixed disk 1 When the edge of the wick has been con- 28 the serrated end 25 is sumedand it is desired to move the same then be turned so as to bring the wick up to top carrying athimble at its upper end which is constructed with a recess 36 the portion of the recess;

theproper position andthen by releasing the stop device the spring immediately throws it into engagement with the operating wheel. Itwill-thusbe seen that I provide an eX- ceedingly simple and highly 'eflicient'wick stop in connection with the wick raising spindle thereby rendering it impossible to move the wick beyond the predetermined adjusted position and at the same time elimihating the use of radially extending arms;

which have heretofore been projected across the line of travel of the wick for the purpose ofstopping the same. 1-

In connectlon with my novel form of wick sto'pI employ a. novel form of lifter for the flame spreader the purpose of whichis to Q quickly and easily elevate the flame spreader the proper distance after the wick has been brought up to the proper lighting position and inthis connection I would state that in ,practiceI prefervto indicate upon the flange '20 alightingpoint 30 to whichthe foot piece can be moved and which is. so positioned with reference to the stop shoulder as to place the wick, in the most advantageousposition for lighting. v i

-: The flame spreader may be of any'suita-ble ondesired construction and herein I have illustrated one consisting of the top 31, cone body. 32, flange 33, and spreader body34: the

lower inner=edgesof which are roundedor tapered as shown at 37 in order to provide an openingsomewliat larger than the main The flame spreader normally rests upon the upperspanner 38 positioned in the inner wick tube andpass- 1 ing upwardly through? the spanner vand 410- through the flame spreader is the lifting rod 40 the upper end? thereof fitting into the recess 36 of the thimble 35. This lifting 7 rod l0passes throughan apertured strap 39 wardly as shown at 45 in order to pass secured within the inner tube adjacent the lower end thereof, and provided with an integral downwardly extending portion 41 "longitudinally slotted as shown at 4:2. The

rod 1 40 after passing through the guiding strip 39' is angledas shown at 43to escape the oil pipe M and is then projected outthrough the slot 42. This rod is preferably swaged so,as to'provide the laterally projecting fins or ribs l6 which engage the rear side of the depending portion l1 and cause the lifting rod to travel in a straight line through the strap 39'and central spanner 38. The outer end of the lifting rod iscurved toprovide-a suitable handle and when this end is movedupwardly asshown in dotted lines the lifting rod is moved vertically carrying the flame spreader upv sufficiently to expose the end of wick so that the lighting Ioperation can be quickly and easily accomplished and the thimble is so shaped with flange having an locking member and disk.

I reference to the up per end of lifting rod that the spreader will have a limited rocking movement thereon thereby facllitating the lighting operation as the flame spreadercan simple and efficient constructionof wick stop and flame spreader lifter capable of ;connectiontooil or vapor: burners of the type now in use.

I claimis v- 1. .In an oil burner, the combination with a wick holder and Iawicktherein, of an elongated tubularbearing attached to said 'wick stop mechanism hereinbefore referred to. It will thus be seenthat Iprovide a Havingthus describedmy inventiomwhat i holder, a spindle in said tube having at one [end means for engaging the wick and at the other enda serratedihand wheel,.a disk carried by said. tubular bearing and spaced fromv said wheel, a locking member carried and a spring interposedbetween saidimemher and tllGdlSkySiLld disk having astop in by said bearing 'andhaving one end in en- J gagement withtheserratlons on said wheel the path of the locking member and also-a latch 'for holding said member out of engagement with the, serrations against the tension of the spring. 1
